safe

Practical equipment access and layered protection capabilities help reduce personnel exposure during commissioning, maintenance and equipment interaction.
 

• Safer access
  Front-access wiring and customer connections reduce the need to work near live cable terminations or live buses.
• Remote breaker operation
  Multiple remote breaker operation options and remote-racking allows qualified personnel to operate the breaker from a safe distance.
• Separation and protection
  Insulation, isolation and compartmentalization help separate energized areas and support safe equipment interaction.
• Advanced protection with fewer external components
  Integrated RELT, MDGF, and arc flash sensing simplify design, installation, and maintenance while improving safety.
• ReliaGear SG 3.0 - Device Limited Arc Resistant (DLAR)
  Integrated arc quenching technology that protects personnel and equipment from damage, rated Type2B in compliance with C37.20.7 (releasing in 2027)

reliable

A proven switchgear foundation, modern components and connected visibility help support dependable operation throughout the equipment lifecycle.
 

• Speed and certainty
  Pre-engineered, modular designs reduce lead times and delivery uncertainty—giving customers the confidence to meet critical project schedules. Plus, standard modules enable on-demand stocking and late-point configuration for even faster delivery.
• Greater system visibility
  Local and remote monitoring options provide access to key system and component information, status, metering and alarms.
• Enhanced thermal performance
  A simplified mid-bus design helps reduce internal losses.
• Improved serviceability
  Standardized assemblies and accessible parts information simplify maintenance and replacement-component identification.
• Life cycle support
  ABB expertise and service resources help support long-term equipment performance and evolving system needs.
